    Product Description

    ITSA1 is a cell-permeable benzotriazole amide that blocks TSA action, reducing TSA-induced acetylation of histone and tubulin in A549 cells when given at 50 µM.1 At the same concentration, ITSA1 also prevents TSA-mediated cell cycle arrest and apoptosis.1 It similarly blocks the action of the HDAC inhibitor SAHA (Item No. 10009929), preventing SAHA-induced hyperacetylation of tubulin in A549 cells.1 ITSA1 reduces TSA-regulated transcription in mouse embryonic stem cells and in zebrafish.1

    WARNING This product is not for human or veterinary use.
